<!-- Proof of concept of running cool.html in an iframe. Also
     shows how to, from outside the iframe, invoke Python scripting in
     the underlying LibreOffice instance that manipulates the document
     being edited.

     This demonstrates using the Python InsertText.py and Capitalise.py
     scripts from javascript across iframes.
